How Transparency Is Changing Trust in Dog Health Products

U.S. pet industry spending reached $158 billion in 2025, according to the American Pet Products Association, with further growth projected for 2026. As the market expands, dog parents face a growing range of products promising support for digestion, mobility, skin and dental health.

For brands and retailers, that growth brings a harder commercial question: how to help buyers tell meaningful quality information apart from marketing claims. The companies that answer it well are likely to earn more repeat trust than those that rely on packaging and star ratings.

Why Trust Has Become the Competitive Edge

The scale of the category explains the pressure. In its March 2026 State of the Industry announcement, APPA reported the $158 billion total for 2025 alongside a $165 billion projection for 2026. Its industry statistics page lists supplies, live animals and over-the-counter medicine at $34.4 billion under 2025 actual sales.

Spending that size draws new sellers quickly. Dog supplement brands now launch through their own websites, marketplace listings and pet specialty chains, often with similar packaging and similar promises. When products look alike, the information a brand can back up becomes one of the few reliable ways to stand apart.

Retailers feel this as well. A store deciding what to stock has to judge supplier claims on behalf of its shoppers, and every product on the shelf carries the retailer’s reputation along with the brand’s.

What the Rules Say, and What They Don’t

Many shoppers assume that supplements for dogs follow the same rules as vitamins for people. They don’t. Under federal law, the FDA evaluates animal products as food or drugs based on their intended use. AAFCO explains that there is no separate federal “dietary supplement” category for animals. It also develops model labeling regulations that many states use as the basis for their own requirements.

AAFCO also notes that claims on animal feed labels are limited to the taste, aroma or nutritive value of the product. Labels may not claim to diagnose, cure, treat or prevent disease, or to alter the structure or function of the body beyond what the nutrition itself provides.

Careful wording alone does not establish regulatory compliance. The intended use of a product, its claims and the broader marketing context all matter. Buyers can treat clear, appropriately qualified explanations as a starting point, but should not assume that a claim is compliant or scientifically supported because it avoids promising a cure.

Quality Signals and What Each One Shows

Manufacturing certifications and laboratory testing can help buyers assess quality controls, but their scope matters. Ask what facility or process a certification covers, which contaminants or product characteristics were tested, and whether the available documentation relates to the ingredients or the finished product. These details offer more useful evidence than a general claim that a product is premium or scientifically formulated.

Each common signal answers a narrower question than it may seem to:

Facility standards (GMP, SQF): These describe how a facility manages production and food safety. They do not, on their own, confirm the quality or effectiveness of every finished product made there.
Independent lab testing: A test supports conclusions only about what it measured, such as a specific contaminant or ingredient level.
Certificates of analysis: These are useful when the buyer knows which ingredient or batch they cover and what the results show.

Some brands gather this information in one place. For example, the bernies dog health products homepage displays its GMP and SQF facility standards, independent lab quality testing and U.S. manufacturing information alongside its product line. That gives a buyer a clear starting point, and the follow-up questions stay the same for any brand: what the certification covers, and what the testing measures.

The Evidence Behind the Benefit

Manufacturing records show how a product is made. They say less about whether its ingredients suit a particular dog. A second line of questions looks at the formula itself: is there relevant research behind the proposed benefit, and does that research involve dogs, the ingredient in question and amounts close to what the product contains?

Individual needs matter here too. A pup’s age, size, diet, activity level and existing health conditions all shape whether a product is a sensible addition. Quality of life is a better measure than a single symptom, and a product that is well made can still be the wrong fit.

This is where a veterinarian adds the most value. A vet who knows the dog can say whether a supplement may help with a specific need, whether it could interact with a current medication, and whether a symptom points to something that needs medical care instead of a daily chew.

Reading the Label With the Right Expectations

Label formats vary across animal products, so the aim is to read what is there carefully rather than expect every package to look the same.

Start with the ingredient declaration and any other label information that applies, such as a guaranteed analysis. Then read the directions for use and check them against the dog’s size and current diet. Where a brand offers supporting documentation online, it can fill in detail the package has no room for.

Lot numbers and expiration dates are worth checking as well. These identifiers can help with traceability if a quality question arises, though they do not by themselves confirm how well a company runs its quality control or recall procedures.

Clarity in all of this is a useful comparison point between brands. It is not proof of formulation quality, and it works best alongside the evidence questions above.

What Transparency Means for Brands and Retailers

For suppliers, substantiation is becoming part of the product. Brands that can document facility standards, describe the scope of their testing and point to research behind their ingredients make it easier for retailers to evaluate them, and easier for store staff to answer informed questions at the shelf.

For retailers, the same documentation supports better supplier selection. Asking for certification scope, testing results and the basis for each claim before stocking a product is a reasonable form of due diligence, and it gives staff something concrete to share when shoppers ask what makes one chew different from another.

Transparency can help a brand stand out in a crowded category. It does not replace evidence of product quality or effectiveness. As dog parents grow more careful with both their budgets and their pups’ health, the brands and sellers that can show their work, rather than just describe it, are in the strongest position to keep their trust.
